A) \[19.3\times {{10}^{4}}\]
B) \[17.8\times {{10}^{4}}\]
C) \[24.93\times {{10}^{9}}\]
D) \[17.8\times {{10}^{8}}\]
Correct Answer: B
Solution :
Most probable velocity\[=\sqrt{\frac{8RT}{\pi m}}\] \[T=(27+273)=300\,K\] Molecular mass of\[{{H}_{2}}=2g\,mo{{l}^{-1}}\] \[=\sqrt{\frac{8\times 8.314\times {{10}^{7}}\times 300}{3.14\times 2}}\] \[=17.8\times {{10}^{4}}\,cm\text{/}s.\]
